ne. eeasee.

To all'whem t may coneer:

Be itknown that I, EARLL C ABE,.&. t-

zen of the United States, residin'g at Indian reference to attachments that are adapted to be connected either permanently or detachably to Well-known types of phonographs that are not Originally construeted as repeating machines and not Coin-controlled, the attachments When applied to such machines enabling them to repeat the records that V may be on their mandrels and rendering the machines ca able of being ecin-controlled.

Objects o the invention are to provide improved and sim le attachments for phonegraphs and simi ar instruments and adapted to be constructed at relatively small expense for converting simple phonographs into eoincontrolled repeating instruments, which at-' taehments may be 'adapted to be readily removed from the instruments.

The invention consists in a phonograph attachment comprising brake-operating mechanism for stopping the instrument at the end of the record and improved mechanisn adapted to be 'put in motion by coins for rcstarting the instrument, so as to repeat the record, the attachment being designed to cooperate With phonographs that have reproducer-arms mo vable on guides and carrying movable devices that nay be interposed between the guides and the reproducer-arms for holding the reproducers away from the records.

The invention consists, further, in the novel parts and in the novel combinations and arrangement of parts, as hereinafter particularly described, and pointed out in the ap ended claims.

eferring to the drawings, Figure 1 is a front elevation of a honograph having the improvement applied in a eabnet, shown in section, of which arts are broken away; Fig. 2, a top plan o the -peei ficatien of Lettere Patenta. Application me June 23, 1905. Serial No. 267338.

being shown in section on a plane above the phonegra )h; Fig. 3, a transverse sectional view on t e line A A in Fig. 2, showing the parts of the instrument in proper position to o erate Fig. 4, a fragmentarjv top plan view s oWing the reproducer near the end of its travel; Fig. 5, a transverse sectional view similar to Fig. 3 except that the reproducer is elevated, as When returning to repeat. Fig. 6, a fragmentary top plan View showing the reprodueer at the end of its travel, as When locked at rest ready to be released to return; Fig. 7, a fragmentary enlarged detail View showing parts seen in Fig. l Fig. S, an elevation of the devices that coperate terelease and elevate the reproduecr, so that it may return for. re eating; and Fig. 9, a perspective view of t e part that causes the reproducer to be replaced into contact with the, record for repeating at the beginning of its travel.

Similar reference characters in the dillerent figures of the drawings designate like elements orfeatures.

The phonograph as heretofore eonstructed compr'ises among its essential elements aease a for the motor mechanisn 'and having a cover b for sup orting the npper Works of the instrument. i n the present invention these need not be elaborate in design, since the ease is incl'osed in a suitable cabinet 10, being supported on brackets 11 and 12 thereof.

Other features of the honograph are a driving-belt c, driven by -t' ie motor and driving a m'andrel B, mounted on a base d, that rcsts on .the cover b and directly supports the upper Works, a record e, a guide f, a reproducer-arm g, mounted on the guide and having an integral reproducer-head in which n reprodueer is nounted, the arm (7 also having a controller eon ;rising an integral head h provided with a sl ioulderiand lipsjand forward of the shoulder, the -lips supporting a guide-pin D, movable longitndinally,'that has a 'stop-pin l arranged between the lips, a guide-bar m for guiding the reprodueer, a feed-screw n, a nut earriedby the base of the arm g, and a reprml ucer-lever q.

. The eabinct ll) may be made in various designs and normally closed, and in the top thereof is a eoin-slot 13, henen! h which a Coinehute 14 is supported that leads to a suitable point above a hopper 15, emptying into u suitable bin 16, with which the cabinet is provided to receive the coins. The repro machine and the improvement, the cabinet ICO c'able 19 is connected to the lever q and runs over the sheave, a Weight 20 being attaohed to the end of the c'ordf A particularly novel part of the invention comprises 'a stand I, having a base r, in which s 'a slot s to receive a securng-screw t, whch' holds the base adjustably upon the cover b, the stand being near the frontof the guidebar m near the terminal end thereof and hav-` ing a projection u and supporting a verticallyswinging arm J, that is mounted at one end thereof on a pivot e which is attached to the stand, the arm being normally held upwardly against a suitable stop e by a spring w, that is'mounted on the stand. The arm J has a recess x in its top near the free end thereof.

- A latch-arm K is mounted on a pivot 21, that is attached to the rojection u of the stand I and has a catch-p ate y adapted to be engaged by the free end. oi" the arm J to push the latch-arm aside When the arm J descends the catchlate then eng'a'gng the top 22 of the end -o' the arm J to lateh it in its depressed position. The latch-arm K is provided with a lever L, that-extends under the terminal or discharge end of the coin-chute 14, and this lever may be of any required I length and shape tor the purpose designed.

The stand I is provided *wth a lateral guide 23, against whichthe in D may he pressed by the arm J a guide hi being ettaehed to the stand and the guide 23 supporting a uide M'. The lever L is normally presse( upi wardly and the latch-arn pressed against a stop 24 by a spring 25, the stop and the s ring being mounted on the projection u of t e stand l.

A guide-base comprising connected opposing parts N and N' is clamped by a screw 0 to the guide-bar m and sup orts an obliqueangled guide P upon the guide-bar to be 'engaged by the inne-r end oi" the pin I) for foreng the pin froni the guide-bar on the return oi' the reprodueer.

' A cellar Q, having a cushion lt, is attached to the guidef for stopping the arm 9. i

Phonographs of the character shown each I have a slot 26 in the base (l, and a breke-lever that is connected to brake nechanism of the motor extends through the slot for manual manipulation of the brake. In order to operate the brake automatically, as is required in ecin-controlled apparatus, a elamp S is attached to the lever 27 and a reach-red 'l` is attached to the clamp and, extends along the front of the guide-bar m toward the terminal thereof andhas an upturned end 28, adapted to be engaged by the head h after the-reproducer has travcrs'ed the record. The brekelever 'is held in its inoperative position by a suitable sprin U.

In practice use, having first preparedthe phonograph for' operation, the motor thereof may be started, and When the pin D moves upon the arm J the pin will^be prevented from rising by engagng the under side of the guide 23, and thereby the arm J Will be compelled to move downwardly to, permit the pin to pass onward to the end of its traveling distance, and as the arm J deseends its end 22 Will push back the arm K and pass under and. be latched by the plate y, the pin 'D moving a short distance n the recess x until theh'ead h engages the end 28, resu1tng in a movement of the lever 27 and a gradual sto v ping of the whole phonograph'machinery, t e nut p remainng in' contact with the feedscreW n and preventin release, of the breke;

A coin may be inserte in the slot 13 and alloWed to descend the chute 14; from which it must fall upon'the lever. L and thence into the hopper 15. The impact ofthe coin on `the lever will cause the eatch-plate y to be retracted, se as to allow the' arm J to rise, eh-

gagingthe pin D and lifting the head h, s' as to remove the shoulder t'thereof from the uide-bar m, the nut p'being simultaneously isengaged from the.feed-screw n. 'At the same time the head 'h will release the reachrod T and thesprin U Will retract the brakelever 27', ,so that t ebrake will release the motor, permitting the restarting of the motor and the entire machinery. The arm J Will elevate the pin D, so that the letter may ride temporarily On the guide M" While the reproducer begins to return, and the guide M Will force the in D onto the guide bar m, the re- Eroducer eing returned to its starting-p0nt y means of the Weight 20 and its connections or other equivalent device that may be rovded. When the reproducer arri'ves at its starting-point, the pin D Will enga ge the guide P, and thereby be' forced forwardly from the uide-*bar m, and thus permit the head JL -to escend onto the guide-bar and the reproducer to descenduntil the contact-piece X engages the record, when the record Will be repeated and the operationscease at the end thereof, as above described, to be again begun only by the use of a coin, asbefore. u
